NBC Connecticut was at the home on Thursday night when police were at the scene for about an hour and officers took items in brown paper bags from the house. Officials said on Friday that police were given consent to go into the home.

There is a joint investigation into the facts and circumstances surrounding the disappearance of 54-year-old Linda Carman, according to police in South Kingstown, Rhode Island, and it includes federal law enforcement agencies, as well as state law enforcement in Connecticut, Vermont and Massachusetts.

Linda Carman has not been seen since she and her 22-year-old son, Nathan, went fishing on Sept. 17.

The mother and son failed to return from a fishing trip in their boat, the Chicken Pox, from the waters off Point Judith in Rhode Island.

For the next six days, the Coast Guard searched a span of 62,000 miles, from Block Island to New Jersey, but called off the search when nothing turned up.

Nathan later told the Coast Guard that he heard a "funny noise" coming from the boat's engine compartment when they were at sea. When he went to go look, it was filling up with water. Then he got into the life raft and called for his mother, but could not find her.

"I got to the life raft after I got my bearings and I was whistling and calling and looking around and I didn't see (my mom)," Carman told the Coast Guard.

Nathan Carman now lives in Vermont and officials have searched his home there as part of the investigation. The search warrant affidavit says police "believe that evidence relating to the crime of RIGL 46-22-9.3 {Operating so as to endanger, resulting in the death} will be located inside Nathan's residence located at 3034 Fort Bridgemon Road in Vernon, Vermont."

A friend of the family told investigators that Linda Carman said the pair was going fishing at Striper Rock, which is located approximately 20 miles off of the Block Island shoreline, according to the affidavit.

However, another witness told police that Nathan Carman said they were going fishing at the Canyons, which is approximately 100 miles off the Block Island shore, the affidavit reads.

When Carman was rescued about 100 miles off shore of Martha's Vineyard, he told investigators he and his mother were fishing on the Block Canyon for tuna, the affidavit said.

The 22-year old told The Associated Press on Wednesday that he had nothing to do with his grandfather's unsolved slaying and didn't harm his missing mother.

While the investigation into what happened to Linda Carman is ongoing, Petty Officer 3rd Class Nicole Groll said during a news conference on Monday that the chances of Linda Carman's survival are minimal.
